Sabre tooth blenny inaccuracies about what is a harp tail blenny!

I’ll be dammed!! The books and on line have it all wrong! They say the what looks like non fanged harptail is the same name as the lineatus sabre toothed harptail, it’s the same fish, no it isn't? They are the same fish name, but one has huge fangs the other doesn't! This is it, lol-- https://www.google.com.au/search?q=yellow+lined+harptail+blenny&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiezeKwnKLhAhUPFHIKHWzZD_MQ_AUIDigB&biw=1366&bih=620#imgrc=RYq5MlXyhDIseM:&spf=1553686287921

Many, I assume, would have noticed the new info on invaluable uses for substances found on the sabre tooths fangs?
This one of those stories.

Some of us ocean lovers have felt the wrath of these little guys fangs and the way the bite does not like to stop bleeding or initially hurt in the normal ways!
There are more then just this variation of fang blennies, but this is more so about the incorrect info in the museums book on Queensland's Moreton bay life and the way the news incorrectly professed that these guys are mimicked, when they are the actual mimickers of the harp tail blenny!

The sabre tooth species in this case, being the fallax of the petroscirtes family being most of the fang blennies, there are more like the plagiotremus group and these guys are more savage, these will use their fangs and bite us!
These guys mimic many blenny species more so the cleaner wrasse as does the other fang blenny being the false cleaner wrasse!
All these mimic so they can fool the fish into a close position, then attack, taking off scales or flesh.

These are the fangs of an other sabre tooth, same thing!


This is the very reef safe, harmless and lovely natured mid stream feeding Meiacanthus lineatus harp tail. Most blennies that do this are all sabre tooth blenny species and in that group are the harp tails! As found by Rudie H. Kuiter, in his book "Guide to sea fishes of Australia", he describes two sabre tooth species as harp tails, but in other books its only defined as a sabre tooth or fang blenny. This one has no obvious fangs, but with the use of an electron micro scope, the fangs are there but are on the verge of being evolved away from, so they are very tiny and near impossible to see, so the Meiacanthus lineatus and luteus are harp tails and sabre tooth blennies.

This the sabre tooth, this one goes from near grey to bright yellow, depending the situation or whom it wants to mimic, usually the harp tail!
